conclusions despite the widespread use of 2d lvef and its good agreement with ventriculography, strain analysis seems to be more reliable as a quantitative tool for ventricular assessment. results the lvef values obtained by the two methods of ventriculography and echocardiography were not significantly different. the highest correlation regarding the echocardiographic lvef was obtained in the ...

background and aim: iron overload in patients with thalassemia major is one of the most important complications of this disease and its cardiac complications are the most important causes of death in these patients.mri t2 is the perfect device to assess the amount of iron deposited in the heart of thalassemia patients, but it causes waste of time and also is an expensive diagnostic method. tiss...

t akotsubo cardiomyopathy (tcm), also known as stress-induced cardiomyopathy, is a clinical syndrome of transient left ventricular (lv) apical wall motion abnormality with relative preservation of the basal heart segments in the absence of any significant atherosclerosis. recurrence of this condition is rare. we report a postmenopausal woman, who experienced two episodes of tcm within 4 months ...

echocardiography is a non-invasive diagnostic technique which provides information on cardiac morphology, function, and hemodynamics. it is the most frequently used cardiovascular diagnostic test only after electrocardiography. in less than five decades, the evolution in this technique has made it the basic part of cardiovascular medicine. herein, the evolution of various forms of echocardiogra...

Objective- to determine the range of systolic times intervals using Pulsed-wave Doppler and m-mode echocardiography in normal, healthy Great Dane dogs. Design- Descriptive study. Animals- Thirty healthy Great Dane dogs. Procedures- This study examined 30 clinically healthy Great Dane dogs by the twodimensional, M-mode and Pulsed-wave Doppler echocardiography. The dogs were awake and unsedated. ...

introduction: aortic valve sclerosisis considered as a manifestation of coronary atherosclerosis. recent studies demonstrated an association between aortic valve sclerosis and obstructive coronary artery disease. the purpose of this study was to evaluatethe correlation betweenaortic valve sclerosis andobstructive coronary artery disease and the extent of coronary artery disease in patients hosp...

pulmonary arterial hypertension (pah) is a progressive disease with high morbidity and mortality rates. research has shown that pah has a prevalence rate of 10-79% in thalassemia major patients. this cross-sectional study was carried out in 2014 to determine the prevalence and risk factors of pah in all thalassemia major patients of over 18 years of age in ilam, iran. a cardiologist measured sy...

dobutamine stress echocardiography (dse) has been widely used as a diagnostic and prognostic modality in the management of stress. dse is associated with limited complications and adverse effects on the health of patients. in this case report, we described a 42-year-old female patient with dobutamine-induced coronary artery spasm with history of exertional dyspnea, which had deteriorated recent...

introduction left ventricular (lv) twist is believed to store potential energy and plays an important role in generating diastolic suction. recent advances in echocardiography techniques have allowed quantification of lv twist. the aim of the present study was to compare lv twist and torsion in healthy human subjects determined by velocity vector imaging (vvi) and tissue doppler imaging (tdi) a...
